IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 153,290, dated July21,1874; application filed June 6, 1874.

To all whom 'it may concern:

Be it known that we, CHARLES F. WILKIN- soN, REUBEN MooHAMEEJAcoB B.ZIEGLEE, and CHARLES SNYDER, of Latimer, in the county of Luzerne andState of Pennsylvania, have invented anew and Improved Car-Coupling, ofwhich the following is a specification In the accompanying drawing,Figure l represents a vertical longitudinal section of my improvedautomatic car-coupling, and Fig. 2 a top view ofthe same.

Similar letters of reference indicate corresponding parts.

Our invention relates to an improved selfacting car-coupling for mining,freight, and passenger cars, which couples readily with cars having thecommon pin-and-link coupling, and is of simple and strong construction.Our invention consists of a draw-hook with inclined front part, fittedrigidly to the car-frame, and set into a recessed bumperframe, inconnection with a link-shaped clevis pivoted to the hook, and a curvedlatch-piece closing over the end of the same.

In the drawing', A represents the drawhook, which is applied firmly inany approved manner to the bottom frame of the car. The hook A has aninclined and curved front edge, for admitting the ready sliding up ofthe clevis or coupling-link B, which is broader at the front end, andpivoted, by a cross-pin, a, to the rearpart of the hook.Abumpertrame,C,eX tends around thelower part and at both sides of thedraw-hook A, and is suitably recessed, and curved at the sides, forguidingl the link vB toward the hook. rlhe side recesses b ofbumperfrarne C serve to support the link in horizontal position forcoupling. A curved latchpiece, 1), is pivoted to shoulders d of the carend, and anged to t over the upper end of the hook. Its lower end iscurved to project forward off the hook, and serves the double purpose ofassisting' the link in passing over the hook for coupling, and ofsupporting the link thereon for uncoupling the cars.

The coupling connects readily cars of different heights, the link of thelower car being then brought into use. It slides, on the approach of thecars, over the hook, and drops into the recess back ofthe hook,formingthereby the intimate coupling of the cars. For uncoupling, the link isswung up, and taken out of the hook, and the drop-latch being thenplaced into inclined position on the outer side of the latter, ready forthe detaching of the cars Without any chance of recoupling.

Having thus tdescribed our invention, we claim as new and desire tosecure by Letters Patent- The automatic carcoupling consisting' ofdraw-hook A, set into recessed bumper-frame C, pivoted coupling-link B,and drop-latch D, fitting over the end ofthe hook, all constructed tooperate substantially in the manner and for the purpose set forth.
